A really cool 1977 Seacraft appeared on eBay recently. It was turned into a "Batboat". I don't know about that decision but it still is a great lake runabout sports craft. If in 100% working condition.
Bidding didn't meet the seller's reserve and stopped at US $2,600.00, which is very reasonable for a watercraft these days.
All of the black paint would cook anyone who is out on the water with it, IMHO.
The auction description...
